About Ideal Weight Calculation

What is Ideal Weight?

The concept of ideal weight refers to a weight range that is associated with optimal health and longevity based on factors like height, gender, and frame size. There are several formulas used to estimate ideal weight, each with different assumptions and purposes.

Calculation Methods

BMI Method

The Body Mass Index (BMI) is calculated as weight in kilograms divided by height in meters squared. A BMI between 18.5 and 24.9 is considered normal weight. This calculator uses your target BMI (default 22) to calculate an ideal weight.

Devine Formula

Men: 50 kg + 2.3 kg for each inch over 5 feet
Women: 45.5 kg + 2.3 kg for each inch over 5 feet

Robinson Formula

Men: 52 kg + 1.9 kg for each inch over 5 feet
Women: 49 kg + 1.7 kg for each inch over 5 feet

Miller Formula

Men: 56.2 kg + 1.41 kg for each inch over 5 feet
Women: 53.1 kg + 1.36 kg for each inch over 5 feet

Hamwi Formula

Men: 48 kg + 2.7 kg for each inch over 5 feet
Women: 45.5 kg + 2.2 kg for each inch over 5 feet

Limitations

Ideal weight calculations have several limitations:

• They don't account for muscle mass versus fat mass
• They may not be appropriate for athletes or elderly individuals
• Ethnic variations are not considered
• Health can vary significantly within "normal" weight ranges
